Extraction of information on transversity GPDs from $\pi^0$ and $\eta$ production on EIC of China

Abstract

The General Parton Distributions (GPDs) are applied to study the hard Pseudoscalar Meson Production (PMP) at high energies. The PMP amplitudes are be obtained within the GPDs factorization. They are expressed in terms of GPDs convolution functions, which are most essential in PMP reactions. We show that these convolution functions can be extracted from the PMP data in future EIC of China (EicC). Predictions of $\pi^0$ and $\eta$ production at typical EicC energies are performed.
